+ Forward & revealing mid-range & vocals.
+ Top tier clarity/detail retrieval.
+ Widest soundstage. Though over-hyped & not quite out of head experience type.
- Recessed/diffused/veiled/thin body of music without a top of the line amp & DAC
- Bass & dynamics only really appear with proper amping.
- Slight edge & tiniest bit of sibilance to the treble.
- Not full closed back, doesn't isolate well & leaks a lot of sound.
- Grainy resolution.
- Bass isn't tight.
Abyss 1266 Phi
-SUPER hard to drive.
-Fit is ultra finicky.
+ The best separation I've heard from a headphone.
+ Vocals are much more distinctively separated from the music vs the HD800/HEK.
+ Resolution/small details are better heard than the HD800.
+ Feels less prone to sibilance than the HD800.
+/- Soundstage is average. Definitely a more intimate sound presentation.
- Bass & dynamics are lacking for my tastes.
- Slightly overall thin sound signature.
Hifiman HE-1000 V1
+ Very solid soundstage. Just behind the HD800 of all the headphones I heard. Without first doing A/B tests between both, I could have sworn the HEK was almost just as wide.
+ Very thick, weighty, musical & full sounding sound signature. Makes the HD800 kinda sound thin in comparison.
+ Incredibly dynamic & separated. Maybe the best I heard. Only again, 2nd to the HD800.
+ The resolution, fullness, dynamics & soundstage are a nice improvement over the HEX v2.
+/- Sub-bass is good, but not amazing. Nothing spectacular about it like with the Fostex TH-900.
- There is a softness & lack of energy/bite to the sound. Only noticeable when compared with a high energy headphone, like the HD800.
- Midrange is good, but ever so slightly distant/diffuse. Nowhere close to being called V-shaped, just slightly behind other cans that have prominent mids.
+/- the slight softness can be remedied quite a bit with silver headphone cables & V2 earpads.
+/- The softness can also play as a strength because these cans are never fatiguing. Though, electronic music does lack the energy.
+/- The resolution/treble might not be as detailed as the HD800. Could be from the thick bass drowning out some of the smaller treble details.
Hifiman HE-X V2
+ Very good soundstage, nearly comparable to the HD800.
+ Solid sub-bass extension.
+ Neutral sound without sounding thin or lacking in any frequency.
- Mids maybe not as lush & energetic as the LCD-2 & HD800.

- Doesn't scale with higher end equipment.
Hifiman HE-6 (4 screw)

- Smaller more intimate soundstage & separation overall compared to the 4 screw.
- Seems a trifle harder to drive than the 4 screw version
+ Insane sub bass!

- Small enclosed soundstage.
- Reminds me of a warmer closed version of a HD600. Doesn't do any one thing spectacular.

+ Very good sub-bass, somewhere in between the Fostex TH-900 & the Beyerdynamics T1.
+ Similar sound signature to Beyer T1 without being as bright.
- Not true closed back, leaks sound.
- Not quite on the level of HD800 in terms of resolution.

- Massively veiled. Most veiled headphone I've ever heard in my life.
- Incredibly low resolution sounding.
- Mids & treble are non-existent.
